seyhmus.cacina 0:ac4dea3e2894 37 * Desc: Example Code to get algorithm estimation results of Heart rate( HRM) from sensor hub and display it on screen.
seyhmus.cacina 0:ac4dea3e2894 38 * Example starts by monitoring heart rate and reinits WHRM algorithm via a button press (switch button)
seyhmus.cacina 0:ac4dea3e2894 39 *
seyhmus.cacina 0:ac4dea3e2894 40 * Example,
seyhmus.cacina 0:ac4dea3e2894 41 *
seyhmus.cacina 0:ac4dea3e2894 42 * 1. Initializes user interface
seyhmus.cacina 0:ac4dea3e2894 43 * initialize display screen and switch button for algo selection.
seyhmus.cacina 0:ac4dea3e2894 44 *
seyhmus.cacina 0:ac4dea3e2894 45 * 2. Initializes underlying hardware port for sensor hub communication:
seyhmus.cacina 0:ac4dea3e2894 46 * setup i2c comm. inits reset pin and mfio event pin and connects interrupt to mfio pin.
seyhmus.cacina 0:ac4dea3e2894 47 *
seyhmus.cacina 0:ac4dea3e2894 48 * 3. When switched to a minitoring mode
seyhmus.cacina 0:ac4dea3e2894 49 * disables previous algorithm, clears mfio event
seyhmus.cacina 0:ac4dea3e2894 50 * calls default init function for the sensor whose data is used by enabled algorithms. Algorithms are
seyhmus.cacina 0:ac4dea3e2894 51 * registered under sesnor instance for this example. Fcunction
seyhmus.cacina 0:ac4dea3e2894 52 * 1. initialize algorithm config struct enabled
seyhmus.cacina 0:ac4dea3e2894 53 * 2. enable data type to both raw sensor and algorithm data
seyhmus.cacina 0:ac4dea3e2894 54 * 3. get input fifo size to learn fifo capacity
seyhmus.cacina 0:ac4dea3e2894 55 * 4. set fifo threshold for mfio event frequency
seyhmus.cacina 0:ac4dea3e2894 56 * 5. reaenable sensor to acquire ppg data
seyhmus.cacina 0:ac4dea3e2894 57 * 6. enable accompanying accel sensor
seyhmus.cacina 0:ac4dea3e2894 58 * 7. enable switched algorithm
seyhmus.cacina 0:ac4dea3e2894 59 *
seyhmus.cacina 0:ac4dea3e2894 60 * 4. Sensor Hub now starts to write raw sensor/algorithm data to its data report FIFO which
seyhmus.cacina 0:ac4dea3e2894 61 * reports mfio event when data size determined by fifo threshold is written to report fifo.
seyhmus.cacina 0:ac4dea3e2894 62 *
seyhmus.cacina 0:ac4dea3e2894 63 * 5. Example calls SH_Max8614x_data_report_execute() which
seyhmus.cacina 0:ac4dea3e2894 64 * 1. calls SH API's sh_ss_execute_once() function which:
seyhmus.cacina 0:ac4dea3e2894 65 * writes sensor hub's report fifo content (sensor/algorithm data samples) to a buffer(1).
seyhmus.cacina 0:ac4dea3e2894 66 * 2. calls CSTMR_SH_FeedAccDataIntoSH() to send accelerometer data to sensor hub which os required for heart rate
seyhmus.cacina 0:ac4dea3e2894 67 * 3. Parses buffer(1) data to extract numeric sensor and algorithm samples according to enabled algorithms.
seyhmus.cacina 0:ac4dea3e2894 68 * look: whrm_data_rx() , max8614x_data_rx() and sample structs whrm_mode1_data and max8614x_mode1_data
seyhmus.cacina 0:ac4dea3e2894 69 *
seyhmus.cacina 0:ac4dea3e2894 70 * 6. numeric values are written to HrmResult within MAX8614x whrm_data_rx() ... and included as extern in main.cpp
seyhmus.cacina 0:ac4dea3e2894 71 *
seyhmus.cacina 0:ac4dea3e2894 72 * 7. Example calls demoUI_display_algo_estimations() to display result on watch screen
seyhmus.cacina 0:ac4dea3e2894 73 *
seyhmus.cacina 0:ac4dea3e2894 74 *
